Methane is an important greenhouse gas, responsible for around 30% of the rise in global temperatures since the industrial revolution. [58] Methane has a global warming potential (GWP) of 29.8 ± 11 compared to CO 2 (potential of 1) over a 100-year period, and 82.5 ± 25.8 over a 20-year period. [59]
The autoignition temperature or self-ignition temperature, often called spontaneous ignition temperature or minimum ignition temperature (or shortly ignition temperature) and formerly also known as kindling point, of a substance is the lowest temperature at which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark.

Methane, the main component of natural gas, has an autoignition temperature of 580 °C (1,076 °F), [55] whereas gasoline and diesel autoignite at approximately 250 °C (482 °F) and 210 °C (410 °F) respectively.
A large compost pile can spontaneously combust if improperly managed. Spontaneous combustion or spontaneous ignition is a type of combustion which occurs by self-heating (increase in temperature due to exothermic internal reactions), followed by thermal runaway (self heating which rapidly accelerates to high temperatures) and finally, autoignition.

Autoignition temperature. 470 °C (878 °F; 743 K) [15] ... The catalytic conversion of methane to methanol is effected by enzymes including methane monooxygenases.
HCCI's autoignition event is highly sensitive to temperature. The simplest temperature control method uses resistance heaters to vary the inlet temperature, but this approach is too slow to change on a cycle-to-cycle frequency. [11] Another technique is fast thermal management (FTM). It is accomplished by varying the intake charge temperature ...

Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Annotation "(s)" indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. Note that these are all negative temperature values. Methane vapor pressure vs. temperature.
